He didn't change his mind idiot. As Xzato will atest to, he agreed it
almost immediately upon the fall of Bloodloch.

He was given 10 years to set his affairs in order, long enough I think
for anyone. That done, he honoured his word.

Several members of Bloodloch were aware of our requirement that Geryon's
situation be dealt with. The fact that they chose not to share it with
you would suggest that you aren't considered important.

Finally as to why Geryon would prefer to be imprisoned in Enorian,
rather than Bloodloch. The reasons are his not mine, ask him....but
actually establishing facts rather than divining them from the fluff in
your navel isn't really your style is it.

Iereas.
